Specifically, the user auto-link strategy introduced in AAP 2.6 automatically links external Identity Provider (IDP) identities to existing AAP user accounts based on email matching without verifying email ownership. This vulnerability enables a remote attacker to potentially hijack a victim\u0026rsquo;s account and gain unauthorized access to other accounts, including administrative accounts. The attacker achieves this by manipulating the email address provided by the IDP during the auto-linking process. This poses a significant risk to organizations using AAP for identity management, potentially leading to data breaches and system compromise.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAttacker identifies a target user account within the AAP gateway.\u003c/li\u003e\n\u003cli\u003eAttacker creates an account on a configured external Identity Provider (IDP).\u003c/li\u003e\n\u003cli\u003eAttacker configures the IDP account with the same email address as the target user in the AAP gateway.\u003c/li\u003e\n\u003cli\u003eThe target user attempts to authenticate to the AAP gateway using the configured IDP.\u003c/li\u003e\n\u003cli\u003eThe AAP gateway, running version 2.6 or later, automatically links the attacker-controlled IDP identity to the existing AAP user account based on email matching, without verifying ownership.\u003c/li\u003e\n\u003cli\u003eThe attacker successfully authenticates to the AAP gateway using the attacker-controlled IDP account, gaining access to the target user\u0026rsquo;s account.\u003c/li\u003e\n\u003cli\u003eIf the hijacked account has administrative privileges, the attacker can escalate privileges and compromise the entire AAP gateway environment.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-6266 can lead to unauthorized access to sensitive data and systems managed by the AAP gateway.
